Abstact: Multipolarities of <Gamma>-rays in ¹⁵²Nd have been studied by conversion electron measurements in the <beta>^- decay of ¹⁵²Pr. The praseodymium activities were obtained by the thermal neutron fission of ²³⁵U and followed with the on-line isotope separator KUR-ISOL. Conversion electrons and <Gamma>-rays were measured with a Si(Li) detector and a HPGe detector, respectively. The two <Gamma>-rays, 226 keV and 285 keV, were decided to have the multipolarities of the E1 transition. The spins and parities of the 1600 keV and 1542 keV levels were determined to be 3⁺ and 2⁺, respectively.
